FiiO DAC and Headphone Amplifier QX11

QX11 QX13 KA17 DAC and Headphone Amplifier Powerful performance another step up Inheriting the high-performance DNA of the KA17, the QX11 delivers further optimizations in sound quality, power efficiency, and user experience.

As the newest member of the QX series, it represents both a continuation of proven excellence and a new starting point for portable HiFi.

End-to-end TI audio architecture, Powerful and stable performance The QX11 combines dual TI OPA1692 op-amps in the voltage gain stage with four parallel TI OPA1622 op-amps for headphone output, achieving ultra-low noise, ultra-low distortion, and outstanding driving power.

The fully integrated Texas Instruments audio architecture brings out rich detail, expansive dynamics, and consistently stable performance.

End-to-end independent powering, For clean, transparent sound The QX11 employs a four-stage precision power supply design that filters out power ripple and noise stage by stage.

Digital and analog circuits also use independently partitioned power supplies equipped with multiple high-precision, low-noise LDOs.

The same power-supply layout used in professional headphone amplifiers delivers stable, abundant energy and provides a solid foundation for high sound quality.
